All squares are rectangles in if-then form

1 answer:

6 0

a square is when all sides are the same and a rectangle is just if it has four sides so a rectangle cant be called a square because not all sides are the same but a square can be called a rectangle because it has four sides. i don't know if that makes sense

The base of a triangle is 9 inches more than 3 times the height. if the area of the triangle is 105 square inches, find the base

wolverine [178]

So to solve you need to set up equations, Using h as the height. So the base is 9 inches more (+9) than 3 times the height (3h) so 3h+9 equals the base. You have the area so you need to plug in the equation for the base and h for height and divide it all by 2. h(3h+9)/2=105. after you solve that and get h by itself you should get h= 7 and the b= 30

Shirts are 5% off. The original price of one shirt is $15. What is the total cost, in dollars, of a shirt at the sale price, inc

Juliette [100K]

Answer:

$15.75

Step-by-step explanation:

$\frac{y}{15} :\frac{5}{100}$

y × 100 = 5 × 15

100y = 75

100y ÷ 100 = 75 ÷ 100

y = 0.75

$15 - $0.75

$14.25

$\frac{y}{15} :\frac{10}{100}$

y × 100 = 10 × 15

100y = 150

100y ÷ 100 = 150 ÷ 100

y = 1.5

$14.25 + $1.50

$15.75
